NBC has announced its choice to replace the late Tim Russert on the long-running news program "Meet the Press."

Chief White House correspondent David Gregory will take over as moderator of the political roundtable show, it was announced Sunday by NBC News president Steve Capus. In addition to his "Meet the Press" responsibilities, Gregory will also be a regular contributor to and serve as backup anchor for NBC's "Today."

"I'm honored and deeply humbled as I take on this role," Gregory said. "I'm filled with a great sense of purpose as I join a superb team to cover Washington and the world from a treasured platform in our country. Above all, I want to make Tim proud."

NBC's Tom Brokaw has been filling in on "Meet the Press" since the sudden death in June of Russert, who had hosted the program since 1991.
